Well, that message certainly got mangled. Let's try again...
I'd like to take this opportunity to say that I appreciate all your comments about the Sienna. I have talked to Eric, and I respect the folks at Elecraft greatly. It is largely because they took the gamble to start a new kit company when everyone was saying it couldn't be done that the doors have been opened for others. I don't see us as competitors, but rather as two sides of the same coin, hopefully growing the industry so that both companies can prosper, and giving you more choices. In fact, this is one reason the Sienna is not positioned to compete with the K2/100 but to give you a cheaper alternative to the big, expensive Japanese boxes while still being able to build it yourself. At least until Elecraft comes out with a high-end rig, we are in two completely different niches. The Sienna is most definitely not a backpacker's rig! Dave Packard, in his book "The HP Way", said that in the early days of the electronics industry (the 20's and 30's), businesses like HP, Varian, General Radio, Fluke and others shared resources, equipment and techniques so that they could all prosper. Once, when engineers told Dave how HP's board testers had clobbered Genrad's market share, he said he was sorry to hear that, because he and the founders of GR had been friends. I hope you all can see that it should be good for America (and the world) to have more American ham radio companies. We all benefit from the increased "buzz". Just as there was once room for Heathkit, Eico, Dynaco, Knight and others, there is room for all of us today. Frankly, rather than grumbling about competition and how crazy an idea it is to put a PC (easily upgradeable, by the way, to answer one objection) in a radio, we should all be more concerned with the state of amateur radio today and doing all we can to attract new hams - true, died-in-the-wool, build-it-yourself hams - so that we can all continue to enjoy this great hobby. 73, Brian, W0DZ Founder, DZKit _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

It's not a good idea to try to operate the tuner when driving an amp, although sometimes it's useful if you are careful. Probably the best thing to do is to tune the K2 into a dummy load and activate the tuner. This will set the tuner up for a 50-ohm load. Then connect the amp and do not activate the tuner. Most amps should provide an SWR of 1.5:1 or less. -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Not sure if you mean the KAT-2 or the KAT-100, but I drive both my amps
with the KAT-100s in line from both radios. I don't know how the tuner would know the difference between an antenna or an amplifier input network. I just let the tuner cycle (it's real quick) using the tune button the first time I activate the amp. Then use the keyer to tune with dits.

The difference between an antenna and an amplifier input network is that the impedance seen when driving an amplifier changes as the amplifier is driven harder! So you can get a sort of unstable condition in which the tuner tries to match a varying impedance. This is probably not harmful since you are tuning at reduced power, but it's not clear that the tuner will find an appropriate match. That's why I recommend tuning the K2 into a 50-ohm dummy load first, and then using it to drive the amp. -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

Thanks for the advice guys. I am shutting down the K2 for the night and

Hi
If you build the KPA100 into an EC2 box externally and your K2 has a KAT2 the firmware will place the KAT2 into bypass mode and select Ant 1. This is the same as using a amp made by some other supplier except the K2 will not be able to detect the amp. The KAT2 bypass mode and Ant 1 can be selected manually in this case. Another option would be to disconnect the RF cable to the KAT2 and just use the BNC output on the back of the K2.

Well spoken, Brian. Thanks for putting some
perspective on this subject. I, and I'm sure many others, wish you and your company all the success in the world... literally. Long live American capitalism and entrepreneurship.
